Slender spires of pale yellow flowers among clumps of iris-like, grey-green leaves. This summer-flowering perennial is perfect for a sunny herbaceous or mixed border. A good companion for grey and silver-leaved foliage plants, it performs best in well-drained, neutral to slightly alkaline soil. - Garden care: Lift and divide large colonies in spring. After flowering dead-head the faded blooms to prevent the plant from self-seeding.
